Where Do River Otters Play? Extremely social animals, river otters can often be seen in groups playing games. They also love to run and slide on their stomachs. If you spy a river otter in the wild, it's likely you'll catch a glimpse of it sliding on its tummy down a muddy bank and into the water.

(b). Measurement of Energy Btu-also called British thermal unit is the amount of energy required to raise the temperature of one pound of water one degree Fahrenheit. Watt (W/m2 or Wm-2) - a metric unit of measurement of the intensity of radiation in watts over a square meter surface. One watt is equal to one joule of work per second. A kilowatt (kW) is the same as 1000 watts. In the previous section, we developed the concept of energy. We now must be able to measure and quantify it, using a standard set of units. Worldwide, two systems of units of measurement are commoly used today: the Metric System (Systeme International) and the British System. The units of energy described in these systems are derived from a technical definition of energy used by physicists.

watt-hour (Wh) The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. The watt-hour is not a standard unit in any formal system, but it is commonly used in electrical applications. An energy expenditure of 1 Wh represents 3600 joules (3.600 x 103 J). To obtain joules when watt-hours are known, multiply by 3.600 x 103. To obtain watt-hours when joules are known, multiply by 2.778 x 10-4.

1 watt is equal to how many joules? 1 watt = 1 joule/sec. By definition of Watt : The SI unit of power, equivalent to one joule per second, corresponding to the rate of consumption of energy in an electric circuit where the potential difference is one volt and the current one ampere. Because, Watt is the unit for power and Joule is the unit for Work.

1 watt is equal to how many joules? Watts are a measurement of electrical power. The symbol for the watt is W and one watt = one joule per second (joule is the unit of energy). So a 60W light bulb converts 60 joules of electrical energy to heat and light energy every second! Volts are the unit of measurement for voltage.

- Most people can name two units of power, few can name even one unit of energy. And yet, power just means energy flow per unit time. We all know the Watt is a unit of power consumption and have an idea how quickly a 1500 Watt kettle boils water. The unit of energy is the Joule - a Watt is just a flow of one Joule per second. The other popular unit of power is the horsepower. The conversion is that one horsepower = 756 Watts. A 100-HP car would be able to turn a 75,600 - Watt electrical generator, or 75.6 kilowatts.

Work, Energy and Power The unit of power is joules per second or J/s when work is measured in joules and time in seconds. The basic unit of power, 1 J/s is called a watt (W), named after James Watt who made important improvements to the steam engine. By definition, a watt is the consumption of one joule of energy per second. 1 W = 1 J/s.

How many watts are equal to 1 unit in an electricity bill? Watt(W) is unit of power and 1000 watts equals 1 Kilowatt (Kw) .Kilowatt hour (Kwh) is the unit of energy consumed which the unit charged in the electricity bill. If you are using 1 Kw power ( sum of all loads including lights/fan TV etc., if switched on and working at the same time) for one hr your consumption will be 1 Unit.
